Neuroanatomy Exam 3
.
1.3-layered tissue covering brain and spinal cord: meninges
2.meninges protect the , they are important for protection of tissue
and circulation of : CNS, brain, CSF
3.three layers of protection: dura mater, arachnoid mater, pia mater
4.outer, fibrous layer: dura mater "tough mother"
5.dura mater is -layered in the brain and -layered in the spinal cord:
2, 1
6.middle, smooth covering; "spider-like": arachnoid mater
7.the arachnoid creates space that is filled with : CSF
8.inner layer "tender", follows contours of sulci/gyri: pia mater
9.infection/inflammation of meningeal membranes (usually arachnoid or
pia mater): meningitis
10.dura mater named locations: falx cerebri, tentorium cerebelli, falx
cerebelli
11.dura mater within longitudinal fissure, right above corpus callosum:
falx cerebri
12.dura mater between the cerebellum and occipital lobe: tentorium
cerebelli
13.dura mater between 2 cerebellar hemispheres: falx cerebelli
14. = bleeding
= collection of blood in a specific area
the bleed is named for its :
hemorrhage hematoma
location
15.pooling of blood between dura mater and skull: epidural hematoma
16.collection of blood between the dura mater and arachnoid:
subdural hematoma
17.bleeding within the subarachnoid space: subarachnoid hemorrhage
(blood mixes with CSF)
18.venous (drainage) system:
spaces where deoxygenated and circulated collects
space where separates
creates of cavities
2 landmarks: ,
= where all the sinuses come together: blood,
CSF dura mater
network
superior sagittal sinus, internal
jugular vein confluence of sinuses

19.located along the superior edge of falx cerebri: superior sagittal sinus
20.how blood and CSF gets back to heart: internal jugular vein

21.the sudden appearance of neurological symptoms due to disruption
of blood flow to the brain: cerebral vascular accident
22.two types of strokes: ischemic (occlusive), hemorrhagic (bleed)
23.deficiency in blood flow due to the partial or complete blockage of
artery (occlusion): ischemia
24.tissue death: necrosis
25.region of dead tissue: infarct
26.parts of infarct
= core area where necrosis is
= region surrounding that may die: inner
zone outer zone (penumbra)
27.ischemic events caused by:
= blockage originates in artery
= blockage originates somewhere else:
thrombus embolus
28.temporary occlusion of an artery for a brief period; the blockage
naturally dissolves, and status returns to baseline of person: transient
ischemic attack (TIA)
29.TIA:
could observe a variety of
symptoms are and followed by :
signs transient, neurological recovery
30.hemorrhagic strokes are a bleed in the brain due to:: defective
artery aneurysm burst/rupture
31.hemorrhagic strokes named by :
intracerebral hemorrhage = within
subarachnoid hemorrhage = below membrane: location,
cerebrum, arachnoid
32.hemorrhagic strokes damage caused by
bleeds: loss of to areas of brain
added on nearby brain tissue: blood supply
(nourishment) pressure
33. are the most common type of stroke
mortality rate is for hemorrhagic vs. ischemic
strokes size of an infarct is related to the size of the
of occlusion is important to overall effect:
ischemic higher
occluded
vessel
